Modification of a fatigue criterion valid for homogeneous multiaxial stress states to account for the beneficial effect of stress gradients is traditionally performed by modifying the stress terms in the fatigue criterion and thereby introducing new parameters that need to be calibrated. Here the stress terms are left unchanged and, instead, the parameters in the fatigue criterion are modified. Th
The conversion of lignin to potentially high-value low molecular weight compounds often results in complex mixtures of monomeric and oligomeric compounds. In this study, a method for the quantitative and qualitative analysis of 40 lignin-derived compounds using ultra-high-performance supercritical fluid chromatography coupled to quadrupole-time-of-flight mass spectrometry (UHPSFC/QTOF-MS) has been
The LHCb system requires high efficiency muon detection into LHC bunch crossing: 95% into a 25 ns time window. To reach such efficiency many parameters of the detector readout apparatus have to be calibrated and adjusted and its channels must be aligned in time. In addition, essential characteristics must be monitored to guarantee a good working condition of the apparatus (to avoid loss of efficie
The resource-based view explains firms’ value appropriation in buyer-supplier relationships by pointing to sustained differences in economic efficiency across firms. Firms with more efficient resources create more value than competitors, which in turn provides a “protective cushion” against price-/quality competition. However, just as firms may differ in the economic efficiency of their resources
In this paper, two distinct polymer electrolyte fuel cell stack models are constructed: a detailed numerical model (DNM) employing a fine-scale computational mesh and a coarse-mesh approach based on a distributed resistance analogy (DRA) where diffusion terms in the transport equations are replaced by rate terms. Both methods are applied to a 5-cell, high-temperature polymer electrolyte fuel cell
Realization of robust coherent quantum phase slips represents a significant experimental challenge. Here we propose a design consisting of multiple nanowire junctions to realize a phase-slip flux qubit. It admits good tunability provided by gate voltages applied on superconducting islands separating nanowire junctions. In addition, the gates and junctions can be identical to or distinct from each
A lifted turbulent H-2/N-2 flame in a vitiated co-flow is studied using Large Eddy Simulation together with a closure based on perfectly stirred reactors. A part of the closure, chemical look-up tables, are generated to close the filtered temperature equations and to compute local radical concentrations throughout the computational domain. The approach has been used to simulate a lifted turbulent
Objective. Infliximab, an anti-tumor necrosis factor alpha (anti-TNF alpha) antibody, is effective in the treatment of several immunoinflammatory diseases. However, many patients experience primary or secondary response failure, suggesting that individualization of treatment regimens may be beneficial. This study was undertaken to investigate whether serologic monitoring of infliximab bioavailabil
Popular Abstract in Swedish Nuförtiden är det tryckta bokomslaget en självklar del av boken som produkt och konsumentvara. I avhandlingen studeras etableringen av bokomslaget och dess betydelse för omstruktureringen av bokmarknaden i Sverige decennierna kring 1800. Från mitten av 1700-talet blev den färdigbundna boken en betydelsefull del av bokhandelns utbud. Förlag och bokhandel började sälja deThe aim of the dissertation is to examine the significance of the paperbound book on the book market as part of the history of consumption. It is an examination of the materiality of the book, in which the form and function, economics and distribution of the binding during the last century of the hand-press era are studied. The intention has been to show that the ready-bound book was a means for t
The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. The concept of Homog
Shed mediastinal blood collected by cardiotomy suction has been shown to be a large contributor to lipid microemboli ending up in different organs. The aim of this study was to test the separation efficiency on human shed blood of a new separation method developed to meet this demand. METHODS: Shed mediastinal blood collected from the pericardial cavity of 13 patients undergoing cardiac surgery wi
The paper addresses an optimization problem related to dimensioning links in a resilient two-layer network. A particular version of the problem which assumes that links of the upper layer are supported by unique paths in the lower layer is considered. Two mixed-integer programming formulations of this problem are presented and discussed. Direct resolving of these formulations requirespre-selection
The public sphere and public reason have recently become key ideas in global governance, with most scholars expressing related transparency and accountability concerns. This article contends that if transnational public sphere(s) and the use of reason in global policy-making aim to reinforce the common good and justice, they must go beyond the procedural concerns of transparency and accountability
We discuss central exclusive production (CEP) of the tensor χc(2 +) meson in proton-(anti)proton collisions at Tevatron, RHIC, and LHC energies. The amplitude for the process is derived within the kt-factorization approach. Differential and total cross sections are calculated for several unintegrated gluon distribution functions (UGDFs). We compare exclusive production of all charmonium states χc(
Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. Some of the materials have been established for over 100 years, while others are only a couple of decades old.A new flux conductor material has be
Abstract in UndeterminedThe Doughnut fallacy hypothesis posits that many debaters tend to sup- port their arguments using collapsed generalities – such as “democracy” – with pur- ported self-evident positive or negative qualities as philosophical grounding. This will leave an often unexamined hole in the middle of the debate which will stunt delib- erative processes, as it effectively stops delibe
We report on fabrication and optical characterization of GaAs nanopillar (NP) arrays, obtained using a combination of low-cost mask generation by self-assembled silica particles (nanosphere lithography) and dry etching. Tapered structures (conical and frustum NP arrays) are fabricated by appropriate optimization of process parameters. Significant suppression of surface reflectance is observed for
Background: A common trend in the research on 2nd generation bioethanol is the focus on intensifying the process and increasing the concentration of water insoluble solids (WIS) throughout the process. However, increasing the WIS content is not without problems. For example, the viscosity of pretreated lignocellulosic materials is known to increase drastically with increasing WIS content. Further,
In this paper public participation in Swedish municipal traffic planning is studied with the focus onto what extent and how municipalities and consultants interact with participants in traffic-planning processes. Telephone interviews with planners were performed and planners' insight and knowledge of participation methods are analysed in order to give an indication of which prerequisites seem to d
